5-庚基苯-1,3-二醇可用作有机合成与医药化学中间体。它可用于合成各种类型的有机分子,例如聚合物、涂料、树脂和生物活性分子等。
合成方法在干燥的反应烧瓶中,将三溴化硼(11 mL,11 mmol,1 M CH2Cl2溶液)加入到3,5-二甲氧基-1-正庚基苯(5 mmol)的干燥二氯甲烷(40 mL)溶液中。随后,在氩气气氛下将反应混合物置于−78℃反应。逐步提高反应温度至0℃,并在此温度下继续搅拌直至反应完成(大约28小时)。接着,将反应体系转移至-78°C冷井,并加入甲醇以破坏未反应的三溴化硼。恢复至室温后,搅拌40分钟。随后,在真空条件下除去挥发物。用乙酸乙酯稀释残余物,依次用饱和NaHCO3溶液、水和盐水洗涤。分离有机层并使用无水Na2SO4进行干燥,过滤去除干燥剂。最后,将所得滤液在真空下减压浓缩,并通过硅胶柱色谱(45%乙醚/石油醚)进行纯化,即可得到目标产物分子5-庚基苯-1,3-二醇。
Over the last few years, much attention has been paid to phytocannabinoids derived from Cannabis for their therapeutic potential. Δ9-tetrahydrocannabinol (Δ9-THC) and cannabidiol (CBD) are the most abundant compounds of the Cannabis sativa L. plant. Recently, novel phytocannabinoids, such as cannabidibutol (CBDB) and cannabidiphorol (CBDP), have been discovered. These new molecules exhibit the same terpenophenolic core of CBD and differ only for the length of the alkyl side chain. Roles of CBD homologs in physiological and pathological processes are emerging but the exact molecular mechanisms remain to be fully elucidated. Here, we investigated the biological effects of the newly discovered CBDB or CBDP, compared to the well-known natural and synthetic CBD (nat CBD and syn CBD) in human breast carcinoma cells that express CB receptors. In detail, our data demonstrated that the treatment of cells with the novel phytocannabinoids affects cell viability, increases the production of reactive oxygen species (ROS) and activates cellular pathways related to ROS signaling, as already demonstrated for natural CBD. Moreover, we observed that the biological activity is significantly increased upon combining CBD homologs with drugs that inhibit the activity of enzymes involved in the metabolism of endocannabinoids, such as the monoacylglycerol lipase (MAGL) inhibitor, or with drugs that induces the activation of cellular stress pathways, such as the phorbol ester 12-myristate 13-acetate (PMA).
